Hi, I've been trying to use an external thankyou page for my form (using B2J Contact), the page is not part of joomla but it is on my server but after submitting I am redirected to a 404 error page. Why is this? How can I redirect to an external link?

thanks

PS: There is no category for Module B2J Contact so that's why I`m posting in "joomla extension and template requests"
